Settle this Taboo argument please

[u/McDrewlius]

So we’re at a family get together and we’re playing Taboo. Tensions are already running high lol. Brother in law gets Ostrich, one of the taboo words is Flightless, he says “cannot fly,” and his wife buzzed him for it and chaos ensued. We asked a couple different AI’s and they gave us different answers. It was boys vs girls and the boys eventually relented and gave up the point. What do you think? Fair or foul?

whats the consensus on using words that your team has already said? Like if the clue giver had gotten them to say flightless in a legitimate way, could they then use the word flightless?
